It's good to see Israel's intelligence apparatus function effectively. I hope disrupting the chain of command starting from the top will make a ground invasion of Lebanon unnecessary. I also hope the conclusion that Iran's leadership comes to is that they are themselves personally quite vulnerable in the case of a direct conflict.
It disrupts the ability of Hezbollah and its allies to respond to an invasion, but it also might be enough on its own to convince Hezbollah to back down. A simple ceasefire would accomplish Israel's objective against Hezbollah (whereas it wouldn't against Hamas) so an invasion of Lebanon isn't inherently necessary.
